Abstract

Crystalline Au2O3 was obtained by hydrothermal synthesis at
3000 atm and its extended X-ray absorption fine-structure
(EXAFS) at the Au L-3-edge was measured at room temperature. A
detailed full multiple scattering (MS) analysis using FEFF8
theory shows that only a small number of scattering paths
contribute significantly to the EXAFS of Au2O3. Because of the
complex unit cell (low local symmetry) of the Au2O3 structure,
contributions of MS paths are almost negligible. The results
indicate that FEFF8 theory provides a good reference for the
analysis of Au-O phases. (C) 2003 Elsevier Science Ltd. All
